BACKGROUND 1. Field

The present disclosure relates to ultrasound diagnosis apparatuses connected to wireless ultrasound probes and methods of operating the ultrasound diagnosis apparatuses, and more particularly, to ultrasound diagnosis apparatuses paired with a plurality of wireless ultrasound probes and operation methods for displaying status information regarding the paired plurality of wireless ultrasound probes on a display of the ultrasound diagnosis apparatus.

2. Description of Related Art

Ultrasound systems transmit ultrasound signals generated by transducers of an ultrasound probe to an internal part of an object and receive information about echo signals reflected therefrom, thereby obtaining an image of the internal part of the object. In particular, ultrasound systems are used for medical purposes including observation of an internal area of an object, detection of foreign substances, diagnosis of damage to the object, and imaging of characteristics.

Wireless ultrasound probes connected to an ultrasound diagnosis apparatus by using wireless communication are nowadays being developed in order to improve the operability of an ultrasound probe by removing a communication cable for transmitting and receiving ultrasound image data between the ultrasound probe and the ultrasound diagnosis apparatus and eliminating the inconvenience caused by the communication cable.

Advantages and features of one or more embodiments of the present invention and methods of accomplishing the same may be understood more readily by reference to the following detailed description of the embodiments and the accompanying drawings. In this regard, the present embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the present embodiments to one of ordinary skill in the art, and the present invention will only be defined by the appended claims.

Terms used herein will now be briefly described and then one or more embodiments of the present invention will be described in detail.

All terms including descriptive or technical terms which are used herein should be construed as having meanings that are obvious to one of ordinary skill in the art. However, the terms may have different meanings according to the intention of one of ordinary skill in the art, precedent cases, or the appearance of new technologies. Also, some terms may be arbitrarily selected by the applicant, and in this case, the meaning of the selected terms will be described in detail in the detailed description of the invention. Thus, the terms used herein have to be defined based on the meaning of the terms together with the description throughout the specification.

When a part “includes” or “comprises” an element, unless there is a particular description contrary thereto, the part can further include other elements, not excluding the other elements. Also, the term “unit” in the embodiments of the present invention means a software component or hardware component such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC), and performs a specific function. However, the term “unit” is not limited to software or hardware. The “unit” may be formed so as to be in an addressable storage medium, or may be formed so as to operate one or more processors. Thus, for example, the term “unit” may refer to components such as software components, object-oriented software components, class components, and task components, and may include processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, micro codes, circuits, data, a database, data structures, tables, arrays, or variables. A function provided by the components and “units” may be associated with the smaller number of components and “units”, or may be divided into additional components and “units”.

In the present specification, an “object” may be a human, an animal, or a part of a human or animal. For example, the object may be an organ (e.g., the liver, the heart, the womb, the brain, a breast, or the abdomen), a blood vessel, or a combination thereof. Furthermore, the “object” may be a phantom. The phantom means a material having a density, an effective atomic number, and a volume that are approximately the same as those of an organism. For example, the phantom may be a spherical phantom having properties similar to the human body.

Furthermore, in the present specification, a “user” may be, but is not limited to, a medical expert, such as a medical doctor, a nurse, a medical laboratory technologist, and a technician who repairs a medical apparatus.

Furthermore, in the present specification, the terms “first”, “second”, “1-1”, etc. are only used to distinguish one component, element, object, image, pixel, or patch from another component, element, object, image, pixel, or patch. Thus, these terms are not limited to representing the order or priority among elements or components. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In this regard, the present embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. In the following description, well-known functions or constructions are not described in detail so as not to obscure the embodiments with unnecessary detail.

FIG. 1 is a conceptual diagram illustrating an example in which an ultrasound diagnosis apparatus 100 is connected with a plurality of wireless ultrasound probes 201 through 204 and displays status information regarding the plurality of wireless ultrasound probes 201 through 204 connected thereto, according to an embodiment.

Referring to FIG. 1 , the ultrasound diagnosis apparatus 100 may be connected with the wireless ultrasound probes 201 through 204 including first through fourth wireless ultrasound probes 201 through 204 by using a wireless communication method. Although FIG. 1 shows that the ultrasound diagnosis apparatus 100 is a cart type apparatus, it may be implemented as a portable type apparatus. Examples of portable ultrasound diagnosis apparatuses may include, but are not limited to, a picture archiving and communication system (PACS) viewer, a hand-carried cardiac ultrasound (HCU) device, a smartphone, a laptop computer, a personal digital assistant (PDA), and a tablet PC.

In an embodiment, the ultrasound diagnosis apparatus 100 may be an apparatus configured to generate an ultrasound image by processing ultrasound image data received from one of the wireless ultrasound probes 201 through 204 and display the generated image, or be an apparatus for implementing only an image display function without performing a separate image processing function.

Each of the wireless ultrasound probes 201 through 204 may transmit ultrasound signals to an object and receive echo signals reflected from the object to thereby produce reception signals. Each of the wireless ultrasound probes 201 through 204 may also perform image processing on the reception signals to thereby generate ultrasound image data and then transmit the generated ultrasound image data to the ultrasound diagnosis apparatus 100.

Although a total of four (4) wireless ultrasound probes 201 through 204 are shown throughout the specification including FIG. 1 , this is merely an example, and the number of wireless ultrasound probes connected to the ultrasound diagnosis apparatus 100 is not limited to 4. The wireless ultrasound probes 201 through 204 may each be different types of probes having different functions, but embodiments are not limited thereto.

The wireless ultrasound probes 201 through 204 may be connected to the ultrasound diagnosis apparatus 100 by using a wireless communication method. In this case, “connected” may mean a state in which the ultrasound diagnosis apparatus 100 is paired to use at least one of the wireless ultrasound probes 201 through 204. Even when the ultrasound diagnosis apparatus 100 is connected with the wireless ultrasound probes 201 through 204, it does not mean that the ultrasound diagnosis apparatus 100 may use all of the wireless ultrasound probes 201 through 204 to transmit ultrasound signals to the object. “Pairing” is conceptually different from “activation”, as will be described in more detail below with reference to FIGS. 8 and 9 .

For example, the ultrasound diagnosis apparatus 100 may be connected wirelessly with the wireless ultrasound probes 201 through 204 by using local area wireless communication. For example, the ultrasound diagnosis apparatus 100 may be wirelessly paired with the wireless ultrasound probes 201 through 204 by using at least one of data communication methods including a Wireless Local Area Network (WLAN), Wireless Fidelity (Wi-Fi), Bluetooth, Zigbee, Wi-Fi Direct (WFD), Infrared Data Association (IrDA), Bluetooth Low Energy (BLE), Near Field Communication (NFC), Wireless Broadband Internet (WiBro), World Interoperability for Microwave Access (WiMAX), Shared Wireless Access Protocol (SWAP), Wireless Gigabit Alliance (WiGig), and radio frequency (RF) communication.

According to an embodiment, the ultrasound diagnosis apparatus 100 may receive ultrasound raw data generated and digital-converted by a wireless ultrasound probe activated among the wireless ultrasound probe 201 through 204 by using a 60-GHz millimeter wave (mmWave) local area communication method. However, embodiments are not limited thereto, and the ultrasound diagnosis apparatus 100 may receive, through a WLAN or Wi-Fi, ultrasound image data that is used to construct an ultrasound image via an activated wireless ultrasound probe.

The ultrasound diagnosis apparatus 100 may display a user interface (UI) indicating status information regarding the wireless ultrasound probes 201 through 204 on a display 130. According to an embodiment, the display 130 may display a UI indicating status information including at least one of a wireless communication frequency, a connection type, a supported application, a wireless communication method, a communication status, battery charging information, a remaining battery capacity, and a time left for use with respect to each of the wireless ultrasound probes 201 through 204 connected wirelessly to the ultrasound diagnosis apparatus 100. For example, the display 130 may display a first UI 141 indicating a status of a wireless communication connection with the ultrasound diagnosis apparatus 100, a second UI 142 indicating a wireless pairing method for connecting to the ultrasound diagnosis apparatus 100, a third UI 143 indicating a communication method for transmitting or receiving ultrasound image data to or from the ultrasound diagnosis apparatus 100, and a fourth UI 144 indicating a remaining battery capacity or whether a battery is being charged. Furthermore, the display 130 may display a fifth UI 145 indicating ID information of each of the wireless ultrasound probes 201 through 204 connected wirelessly to the ultrasound diagnosis apparatus 100. UIs indicating status information will be described in more detail below with reference to FIGS. 6, 7A, and 7B.

The ultrasound diagnosis apparatus 100 may display on the display 130 connection states of the wireless ultrasound probes 201 through 204 that are connected wirelessly thereto, and embodiments are not limited thereto. According to an embodiment, the ultrasound diagnosis apparatus 100 may output a preset sound when wirelessly connected with the wireless ultrasound probes 201 through 204. Furthermore, in another embodiment, the ultrasound diagnosis apparatus 100 may output different sounds respectively according to ID information of the wireless ultrasound probes 201 through 204. For example, when the first and second wireless ultrasound probes 201 and 202 are respectively connected to the ultrasound diagnosis apparatus 100, the ultrasound diagnosis apparatus 100 may output first and second sounds, respectively.

A conventional ultrasound system including a wireless ultrasound probe includes only one wireless ultrasound probe, or even when the ultrasound system includes a plurality of wireless ultrasound probes, only one of the wireless ultrasound probes may be wirelessly paired thereto. Thus, when a user desires to use a wireless ultrasound probe other than a wireless ultrasound probe currently being paired, the user suffers the inconvenience of having to disconnect the paired wireless ultrasound probe and then pair the desired wireless ultrasound probe again.

On the other hand, the ultrasound diagnosis apparatus 100 according to the present embodiment may be wirelessly paired with the wireless ultrasound probes 201 through 204 simultaneously. Thus, when the user desires to use one of the wireless ultrasound probes 201 through 204, this configuration may allow the user to immediately use the desired wireless ultrasound probe without a separate additional pairing process, thereby increasing user convenience. Furthermore, the ultrasound diagnosis apparatus 100 may display a UI indicating status information including connection states of the wireless ultrasound probes 201 through 204 such that the user may easily identify a wireless connection state, a wireless communication method, and a remaining battery capacity of each of the wireless ultrasound probes 201 through 204.

FIG. 2 is a block diagram of a configuration of an ultrasound system according to an embodiment.

Referring to FIG. 2 , the ultrasound system may include an ultrasound diagnosis apparatus 100 and a plurality of wireless ultrasound probes 201 through 204. The ultrasound diagnosis apparatus 100 may be implemented not only as a cart type apparatus but also as a portable type apparatus. Examples of portable ultrasound diagnosis apparatuses may include, but are not limited to, a PACS viewer, a HCU device, a smartphone, a laptop computer, a PDA, and a tablet PC.

In an embodiment, the ultrasound diagnosis apparatus 100 may be an apparatus configured to generate an ultrasound image by processing ultrasound image data received from one of the wireless ultrasound probes 201 through 204 and display the generated image, or be an apparatus for implementing only an image display function without performing a separate image processing function.

The ultrasound diagnosis apparatus 100 may include a communicator 110, a controller 120, and a display 130. The communicator 110 may be connected simultaneously with the wireless ultrasound probes 201 through 204 by using a wireless communication method. For example, the communicator 110 may simultaneously be paired wirelessly with the wireless ultrasound probes 201 through 204 by using at least one of wireless communication techniques including a WLAN, Wi-Fi, Bluetooth, Zigbee, WFD, IrDA, BLE, NFC, WiBro, WiMAX, SWAP, WiGig, and RF communication method.

According to an embodiment, the communicator 110 may include a wireless communication module for pairing with the wireless ultrasound probes 201 through 204 and a data communication module for receiving ultrasound raw data generated by a wireless ultrasound probe that is activated among the wireless ultrasound probes 201 through 204. The communicator 110 may include a 60-GHz mmWave data communication module and receive raw data via the 60-GHz mmWave data communication module. To acquire the raw data, a wireless ultrasound probe activated among the wireless ultrasound probes transmits ultrasound signals to the object, processes received ultrasound echo signals, and performs analog-to-digital conversion on the resulting signals. The wireless ultrasound probes 201 through 204 may be wirelessly paired to the ultrasound diagnosis apparatus 100 simultaneously, but only one of the wireless ultrasound probes 201 through 204 may be activated. Thus, the communicator 110 may include one 60-GHz mmWave data communication module for performing data communication with the one activated wireless ultrasound probe.

In another embodiment, the communicator 110 may not include the 60-GHz mmWave data communication module. When a wireless ultrasound probe that is activated among the wireless ultrasound probes 201 through 204 directly transmits to the display 130 image data that is used to construct an ultrasound image of the object, a relatively small amount of data may be transmitted compared to transmission of ultrasound raw data. In this case, the communicator 110 may include only a local area communication module for pairing.

According to an embodiment, the communicator 110 may wirelessly receive status information regarding the paired wireless ultrasound probes 201 through 204 respectively from the wireless ultrasound probes 201 through 204. The communicator 110 may periodically receive status information regarding each of the wireless ultrasound probes 201 through 204 to check a state thereof based on the status information. For example, the status information may include at least one of a wireless communication frequency, a connection type, a supported application, a wireless communication method, a communication status, battery charging information, a remaining battery capacity, and a time left for use with respect to each of the wireless ultrasound probes 201 through 204.

The controller 120 may control operations of the communicator 110 and the display 130. In detail, the controller 120 may control the communicator 110 to wirelessly pair the ultrasound diagnosis apparatus 100 with the wireless ultrasound probes 201 through 204 and wirelessly receive status information regarding the paired wireless ultrasound probes 201 through 204. Furthermore, the controller 120 may generate a UI indicating the status information regarding the wireless ultrasound probes 201 through 204, which are received via the communicator 110 and control the display 130 to display the generated UI.

For example, the controller 120 may be formed as a hardware module including at least one of a central processing unit (CPU), a microprocessor, a graphic processing unit, random-access memory (RAM), and read-only memory (ROM). In an embodiment, the controller 120 may be implemented as an application processor (AP). The controller 120 may also be implemented as a hardware component such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). However, embodiments are not limited thereto, and the controller 120 may include components such as software components, object-oriented software components, class components and task components, processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, micro codes, circuits, data, a database, data structures, tables, arrays, and variables.

The display 130 may display a UI indicating status information regarding each of the wireless ultrasound probes 201 through 204 wirelessly paired to the ultrasound diagnosis apparatus 100. According to an embodiment, the display 130 may display a graphical user interface (GUI) graphically representing at least one of a wireless communication frequency, a connection type, an executable application, a wireless communication method, a communication status, battery charging information, a remaining battery capacity, and a time left for use with respect to each of the wireless ultrasound probes 201 through 204. In an embodiment, the display 130 may display a GUI indicating a data communication method for receiving ultrasound raw data or image data acquired from imaging from a wireless ultrasound probe activated among the wireless ultrasound probes 201 through 204.

Furthermore, the display 130 may display characters respectively indicating ID information of the wireless ultrasound probes 201 through 204 and thumbnail images graphically representing shapes of the wireless ultrasound probes 201 through 204.

The display 130 may be constructed by a physical device including at least one of a cathode ray tube (CRT) display, a liquid crystal display (LCD), a plasma display panel (PDP), an organic light-emitting diode (OLED) display, a field-emission display (FED), an LED display, a vacuum fluorescent display (VFD), a digital light processing (DLP) display, a flat panel display, a three-dimensional (3D) display, and a transparent display, and embodiments are not limited thereto. According to an embodiment, the display 130 may be formed as a touch screen including a touch interface. When the display 130 is formed as a touch screen, the display 130 may be integrated with a touch pad to receive a user touch input.

Each of the wireless ultrasound probes 201 through 204 may transmit ultrasound signals to an object and receive echo signals reflected from the object to produce reception signals. Each of the wireless ultrasound probes 201 through 204 may also perform image processing on the reception signals to thereby generate ultrasound image data. The wireless ultrasound probes 201 through 204 may be wirelessly connected to the ultrasound diagnosis apparatus 100 simultaneously via the communicator 110. According to an embodiment, the wireless ultrasound probes 201 through 204 may transmit generated ultrasound image data wirelessly to the ultrasound diagnosis apparatus 100 via the communicator 110.

Although not shown in FIG. 2 , the ultrasound diagnosis apparatus 100 may further include a sound output unit. The sound output unit may output a preset sound when the ultrasound diagnosis apparatus 100 is connected wirelessly with the wireless ultrasound probes 201 through 204. According to an embodiment, the sound output unit may output different sounds respectively according to ID information of the wireless ultrasound probes 201 through 204. For example, when the first and second wireless ultrasound probes 201 and 202 are respectively connected to the ultrasound diagnosis apparatus 100, the sound output unit may output first and second sounds, respectively.

FIG. 3 is a block diagram of a configuration of an ultrasound system according to another embodiment.

Referring to FIG. 3 , the ultrasound system according to the present embodiment may include an ultrasound diagnosis apparatus 100′ and a plurality of wireless ultrasound probes 201 through 204. The ultrasound diagnosis apparatus 100′ shown in FIG. 3 includes the same components as the controller 120 and the display 130 of the ultrasound diagnosis apparatus 100 described with reference to FIG. 2 , except for a communicator 110′, and thus descriptions that are already provided above with respect to FIG. 2 will be omitted here.

The communicator 110′ may include first through fourth wireless communication modules 111 through 114. The first through fourth wireless communication modules 111 through 114 may be paired one-to-one with the wireless ultrasound probes 201 through 204 by using at least one of wireless communication methods including WLAN, Wi-Fi, Bluetooth, Zigbee, WFD, IrDA, BLE, NFC, WiBro, WiMAX, SWAP, WiGig, and RF communication. For example, the first through fourth wireless communication modules 111 through 114 may respectively be paired with the first through fourth ultrasound probes 201 through 204.

The first through fourth wireless communication modules 111 through 114 may transmit or receive ultrasound image data to or from the first through fourth wireless ultrasound probes 201 through 204.

FIG. 6 illustrates an example in which an ultrasound diagnosis apparatus displays status information regarding a plurality of wireless ultrasound probes, i.e., first through fourth wireless ultrasound probes 601 through 604 connected thereto, according to an embodiment.

Referring to FIG. 6 , a display 600 may display in a first region 600-1 a UI including thumbnail images respectively representing shapes of the first through fourth wireless ultrasound probes 601 through 604 connected to the ultrasound diagnosis apparatus and characters respectively indicating ID information of the first through fourth wireless ultrasound probes 601 through 604. As a component of the ultrasound diagnosis apparatus, the display 600 may be attached to a control panel to display a UI, but embodiments are not limited thereto. The display 600 may display an ultrasound image of an object via one of the first through fourth wireless ultrasound probes 601 through 604. The display 600 may display in a second region 600-2 UIs used for operating the ultrasound diagnosis apparatus, e.g., for obtaining an ultrasound image of the object or manipulating the obtained ultrasound image by using the ultrasound diagnosis apparatus.

A UI indicating status information regarding the first through fourth wireless ultrasound probes 601 through 604 wirelessly paired to the ultrasound diagnosis apparatus may be displayed in the first region 600-1. In an embodiment, the UI may be a GUI graphically representing status information. For example, the status information may include at least one of a wireless connection status, a wireless communication method, a wireless communication frequency, and a connection type with respect to each of the first through fourth wireless ultrasound probes 601 through 604.

For example, a first UI 610 indicating ID information of the first wireless ultrasound probe 601, a second UI 620-1 indicating a status of wireless connection between the first wireless ultrasound probe 601 and the ultrasound diagnosis apparatus, and a third UI 630 indicating a wireless communication method used to pair the first wireless ultrasound probe 601 with the ultrasound diagnosis apparatus may be displayed in the first region 600-1 of the display 600. The first UI 610 indicating the ID information of the first wireless ultrasound probe 601 may be displayed as characters, but the second UI 620-1 may be a GUI indicating a wireless connection status as the number of bar-shaped antennas. The third UI 630 may be a GUI composed of symbols indicating Wi-fi, Bluetooth, NFC, WiGig, etc. The number of bars in the second UI 620-1 and the number of antennas in the third UI 630 may be symbols that graphically represent a status of wireless communication between the first wireless ultrasound probe 601 and the ultrasound diagnosis apparatus. For example, in the third UI 630 indicating pairing via Wi-fi, the more antennas that are filled in a fan-shaped antenna symbol may mean the smoother Wi-fi pairing between the first wireless ultrasound probe 601 and the ultrasound diagnosis apparatus.

In the embodiment shown in FIG. 6 , the second through fourth wireless ultrasound probes 602 through 604 may be wirelessly paired with the ultrasound diagnosis apparatus by using Bluetooth, NFC, and WiGig, respectively. Statuses of wireless communications between each of the second through fourth wireless ultrasound probes 602 through 604 and the ultrasound diagnosis apparatus may respectively be displayed via first UIs 620-2 through 620-4.

A fourth UI 640 indicating a method of data communication between the ultrasound diagnosis apparatus and the fourth wireless ultrasound probe 604 activated among the first through fourth wireless ultrasound probes 610 through 602 may be displayed in the first region 600-1. A thumbnail image of the fourth wireless ultrasound probe 604 that is the activated wireless ultrasound probe and its neighborhood may be shown in a specific color or shade to distinguish the fourth wireless ultrasound probe 604 from the first through third wireless ultrasound probes 601 through 603 that are not activated. According to an embodiment, a UI 600 a representing a state of wireless pairing with the ultrasound diagnosis apparatus and a UI 600 b representing a state in which an ultrasound signal is being transmitted to the object, i.e., an activated state, may be indicated on the thumbnail image of the fourth wireless ultrasound probe 604.

According to an embodiment, the fourth wireless ultrasound probe 604 may transmit ultrasound signals to the object, receive ultrasound echo signals reflected from the object, and perform analog-to-digital conversion on the ultrasound echo signals to thereby generate ultrasound raw data. The fourth wireless ultrasound probe 604 may transmit the ultrasound raw data to the ultrasound diagnosis apparatus by using a 60-GHz mmWave data communication method. In this case, a fourth UI 640 may include a UI 640-1 indicating a status of data communication between the fourth ultrasound probe 604 and the ultrasound diagnosis apparatus and a UI 640-2 indicating a method of transmission of ultrasound raw data as “60 GHz”. The fourth UI 640 may be displayed on one side of the thumbnail image of the fourth wireless ultrasound probe 604 that is the activated wireless ultrasound probe.

Furthermore, the display 600 may display in the first region 600-1 a UI indicating a state of a battery embedded in each of the first through fourth wireless ultrasound probes 601 through 604 connected to the ultrasound diagnosis apparatus, whether the battery is being charged, a time left for use, etc. For example, fifth UIs 650-1 and 650-2 respectively indicating that batteries respectively embedded in the first and second wireless ultrasound probes 601 and 602 are being charged may be displayed in the first region 600-1. In the embodiment shown in FIG. 6 , the fifth UIs 650-1 and 650-2 may allow the user to easily identify that the first and second wireless ultrasound probes 601 and 602 are being charged.

In an embodiment, a battery embedded in the third wireless ultrasound probe 603 may be fully charged to 100% while a battery in the fourth wireless ultrasound probe 604 may have 60% charge left. In this case, the display 600 may display fifth UIs 650-3 and 650-4 indicating the remaining battery capacities of the third and fourth wireless ultrasound probes 603 and 604 as geometric shapes or symbols and sixth UIs 660-3 and 660-4 indicating them as percentage (%) figures or characters.

According to an embodiment, the display 600 may display seventh UIs 670-3 and 670-4 respectively indicating remaining usable times of the third and fourth wireless ultrasound probes 603 and 604.

While FIG. 6 shows that the display 600 simultaneously displays second UIs 620-1 through 620-4 indicating a wireless connection status, the third UI 630 indicating a wireless communication method, the fourth UI 640 indicating a wireless communication frequency, the fifth UIs 650-1 and 650-2 indicating whether batteries are being charged, the fifth UIs 650-3 and 650-4 and sixth UIs 660-3 and 660-4 indicating remaining battery capacities, and the seventh UIs 670-3 and 670-4 indicating remaining usable times, embodiments are not limited thereto. In an embodiment, status information may include at least one of ID information, a wireless communication frequency, a connection type, a supported application, a wireless communication method, a communication status, battery charging information, a remaining battery capacity, and a time left for use with respect to each of the first through fourth wireless ultrasound probes 601 through 604 paired to the ultrasound diagnosis apparatus by using a wireless communication method. Furthermore, UIs indicating the above status information may be displayed simultaneously or separately.

FIGS. 7A and 7B are diagrams illustrating examples in which an ultrasound diagnosis apparatus displays information about a status of its communication with a plurality of wireless ultrasound probes connected thereto, according to embodiments.

Referring to FIG. 7A, a wireless ultrasound probe 701 may be connected wirelessly to an ultrasound diagnosis apparatus 700. In an embodiment, the ultrasound diagnosis apparatus 702 may be a cart type apparatus, but is not limited thereto.

According to an embodiment, the wireless ultrasound probe 701 may be wirelessly paired to the ultrasound diagnosis apparatus 702 by using a communication method such as Wi-fi, WLAN, or Bluetooth. Furthermore, the wireless ultrasound probe 701 may transmit ultrasound raw data generated using ultrasound echo signals acquired from the object to the ultrasound diagnosis apparatus 702. In this case, the wireless ultrasound probe 701 may transmit the ultrasound raw data wirelessly to the ultrasound diagnosis apparatus 702 by using a 60-GHz mmWave data communication method. The ultrasound diagnosis apparatus 702 may perform image processing on the received ultrasound raw data to generate an ultrasound image.

A display 710 of the ultrasound diagnosis apparatus 702 may display first through fifth UIs 721 through 725 indicating status information of the wireless ultrasound probe 701. For example, the display 710 may display the first UI 721 indicating ID information of the wireless ultrasound probe 701, the second UI 722 indicating a method of pairing with the wireless ultrasound probe 701, the third UI 723 indicating a status of data communication between the wireless ultrasound probe 701 and the ultrasound diagnosis apparatus 702, the fourth UI 724 indicating a method of performing data communication with the ultrasound diagnosis apparatus 702, and the fifth UI 725 indicating a status of a battery in the wireless ultrasound probe 701.

Although the second and fourth UIs 722 and 724 both indicate methods of wireless communication between the ultrasound diagnosis apparatus 702 and the wireless ultrasound probe 701, they actually indicate different types of communication methods. In detail, the second UI 722 indicates a wireless communication method such as Wi-fi, Bluetooth, etc., via which the wireless ultrasound probe 701 is wirelessly paired to the ultrasound diagnosis apparatus 702, whereas the fourth UI 724 indicates a data communication method for transmitting ultrasound raw data generated by the wireless ultrasound probe 701 to the ultrasound diagnosis apparatus 702.

The second UI 722 and a third UI 723 may both indicate a status of wireless communication between the wireless ultrasound probe 701 and the ultrasound diagnosis apparatus 702. For example, the second UI 722 may indicate that the ultrasound diagnosis apparatus 702 is wirelessly paired with the wireless ultrasound probe 701 via Wi-fi while simultaneously displaying a status of the wireless pairing. In other words, when the number of fan-shaped antennas in the second UI 722 increases, it may mean that wireless pairing is performed more smoothly. Similarly, the third UI 723 may indicate status information about data communication between the wireless ultrasound probe 701 and the ultrasound diagnosis apparatus 702 based on the number of bar-shaped antennas. For example, as the number of bar-shaped antennas in the third UI 723 increases, ultrasound raw data generated by the wireless ultrasound probe 701 may be transmitted to the ultrasound diagnosis apparatus 702 more smoothly.

Referring to FIG. 7B, a wireless ultrasound probe 703 may be wirelessly connected to an ultrasound imaging apparatus 704. In an embodiment, the ultrasound imaging apparatus 704 may be a tablet pc, but is not limited thereto.

The wireless ultrasound probe 703 may be paired with the ultrasound imaging apparatus 704 by using a communication method such as Wi-fi or Bluetooth. The wireless ultrasound probe 703 may include both a beamformer and an image processor, and perform analog-to-digital conversion of ultrasound echo signals and then post-processing of the resulting signals to thereby generate ultrasound image data regarding an object. In this case, the wireless ultrasound probe 703 may transmit the ultrasound image data to the ultrasound imaging apparatus 704 by using a local area wireless communication method such as Wi-fi, WLAN, or Bluetooth. The wireless ultrasound probe 703 may transmit data having a resolution suitable for a table PC to the ultrasound diagnosis apparatus 704 after performing additional image processing on ultrasound raw data.

A display 730 of the ultrasound imaging apparatus 704 may display UIs 741 through 743 indicating status information of the wireless ultrasound probe 703. For example, the display 730 may display the first UI 741 indicating ID information of the wireless ultrasound probe 703, the second UI 742 indicating a method of pairing and data communication with the wireless ultrasound probe 703, and the third UI 743 indicating a status of a battery in the wireless ultrasound probe 703. Unlike the second UI 722 described with reference to FIG. 7A, the second UI 742 may indicate both a method of wireless pairing between the wireless ultrasound probe 703 and the ultrasound imaging apparatus 704 and a method of communicating ultrasound image data therebetween.

In the embodiments shown in FIGS. 7A and 7B, the wireless ultrasound probe 701 and 703 may generate only ultrasound raw data regarding the object or acquire ultrasound image data by performing post-processing of the ultrasound raw data and transmit the ultrasound raw data and the ultrasound image data respectively to the ultrasound diagnosis apparatus 702 and the ultrasound imaging apparatus 704. The wireless ultrasound probe 701 according to the embodiment shown in FIG. 7A transmits to the ultrasound diagnosis apparatus 702 ultrasound raw data with higher image quality and higher frame rate than in the embodiment shown in FIG. 7B. Thus, the wireless ultrasound probe 701 may use a 60-GHz mmWave data communication method for the transmission. In the embodiment shown in FIG. 7B, the wireless ultrasound probe 703 generates ultrasound image data with low image quality and low frame rate by performing post-processing of ultrasound raw data and transmits the ultrasound image data to the ultrasound imaging apparatus 704 such as a tablet PC. In this case, the wireless ultrasound probe 703 may use a communication method such as Wi-fi or Bluetooth for the transmission.

According to the embodiments described with reference to FIGS. 7A and 7B, when the wireless ultrasound probes 701 and 703 transmits ultrasound raw data or ultrasound image data by using different types of communication methods, UIs (722 and 723 of FIG. 7A and 742 of FIG. 7B) indicating data communication methods are respectively displayed on the displays 710 and 730. This allows the user to easily identify a data communication method, thereby increasing user convenience.

The first wireless ultrasound probe 201 generates ultrasound image data by performing image processing on the received ultrasound echo signals (operation S870).

The first wireless ultrasound probe 201 transmits the generated ultrasound image data to the ultrasound diagnosis apparatus 100 (operation S880). According to an embodiment, the first wireless ultrasound probe 201 may transmit the ultrasound image data generated by performing analog-to-digital conversion on ultrasound raw data regarding the object to the ultrasound diagnosis apparatus 100 by using a 60-GHz local area wireless communication method. In another embodiment, the first wireless ultrasound probe 201 may generate a final ultrasound image based on the ultrasound image data regarding the object and transmit the generated final ultrasound image to the ultrasound diagnosis apparatus 100 by using a wireless communication method such as Wi-fi, Bluetooth, etc.
